Abstract: Disclosed are a display substrate. The display substrate includes a drive backplane; a first electrode layer disposed on a side of the drive backplane; a pixel definition layer disposed on a side, distal to the drive backplane, of the first electrode layer; an organic light-emitting layer disposed on a side, distal to the drive backplane, of the pixel definition layer, wherein the organic light-emitting layer comprises: a plurality of organic material layers stacked in a direction perpendicular to and away from the drive backplane, and a portion of the organic material layer disposed inside the partition groove is separated from a portion of the organic material layer disposed outside the partition groove; and a second electrode layer disposed on a side, distal to the drive backplane, of the organic light-emitting layer.

Abstract: A display panel is provided. The display panel includes a driving back plate and a pixel layer disposed on a side of the driving back plate. The pixel layer includes a plurality of pixels, and the pixel includes m color sub-pixels for emitting color light and k white sub-pixels for emitting white light, wherein m and k are both integers greater than 1. The k white sub-pixels are configured to adjust the luminance of the pixel.

Abstract: A display panel includes a plurality of first pixel units, each of the first pixel units including a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel of different colors, and the four sub-pixels including a white sub-pixel. In each of the first pixel units, the four sub-pixels are arranged in two rows and two columns, the first sub-pixel and the fourth sub-pixel are diagonally located and centrally symmetric, the second sub-pixel and the third sub-pixel are diagonally located and centrally symmetric, the first pixel unit composed of the four sub-pixels is formed in a hexagon as a whole, and the first pixel unit has at least two obtuse angles or two arc edges protruding toward a direction away from a center of the first pixel unit.

Abstract: A pixel circuit and a driving method thereof, a display panel, and a display device. The pixel circuit includes a driving circuit, a first switching circuit, a second switching circuit, and a first reset circuit. The driving circuit is configured to drive a light-emitting element to emit light, the first switching circuit is configured to be turned on in response to a first scanning signal to transmit a data signal to a control terminal of the driving circuit, the second switching circuit is configured to be turned on in response to a light-emitting control signal to transmit a first power signal to a first terminal of the driving circuit, and the first reset circuit is configured to be turned on in response to a first reset control signal to transmit a reset signal to the first terminal of the driving circuit.
